DEFINITIONS

MERULAXIS
(Rhinocryptidae; Ϯ Slaty Bristlefront M. ater) Portmanteau of genera Merula Leach, 1816, blackbird, and Synallaxis Vieillot, 1818, spinetail (cf. L. -ax  inclining towards); “I should have rejoiced had the stern laws of priority allowed the appropriate name, Platyurus, Swains., to be retained instead of a name so absurdly constructed as Merulaxis, Less. Few would discover, without being told, that this word is intended as a compound of Merula and Synallaxis” (Strickland 1841); "CXLVII.^e Genre. MÉRULAXE; Merulaxis, Less.   Bec médiocre, alongé, presque droit, assez fort, trés-comprimé, convexe en dessus, à arête marquée seulement entre les narines, à pointe un peu dentée, crochue; à mandibule inférieure mince, droite, légèrement convexe en dessous; derrière de l'œil nu; narines latérales, amples, recouvertes par une membrane et par les plumes du front, qui sont rigides et dressées; ailes très-courtes, concaves, à cinquième, sixième, septième et huitième rémiges égales et les plus longues; queue longue, rectiligne, à rectrices élargies et molles; tarses alongés, minces, scutellés.    1. MÉRULAXE NOIR; Merulaxis ater, Less., Cent. zool., pl. 30.   ...   2. MÉRULAXE ROUX; Merulaxis rutilus." (Lesson 1831); "Merulaxis Lesson, Traité d'Orn., livr. 5, end of 1830 or beginning of 1831, p. 397. Type, Merulaxis ater Lesson.¹   ...   ¹ This genus as originally constituted contained two "species," M. ater and M. rutilus; the former is the ♂, the latter the ♀ of the same species." (Peters 1951, VII, 281).
Var. Merularis.
Synon. Platyurus, Sarochalinus.
